HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 419, 42969 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 419, 42969 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 419, 42969 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 419, 42969 is 1.

HCF(419, 42969) = 1

Highest Common Factor of 419,42969 using Euclid's algorithm

Highest Common Factor of 419,42969 is 1

Step 1: Since 42969 > 419, we apply the division lemma to 42969 and 419, to get

42969 = 419 x 102 + 231

Step 2: Since the reminder 419 ≠ 0, we apply division lemma to 231 and 419, to get

419 = 231 x 1 + 188

Step 3: We consider the new divisor 231 and the new remainder 188, and apply the division lemma to get

231 = 188 x 1 + 43

We consider the new divisor 188 and the new remainder 43,and apply the division lemma to get

188 = 43 x 4 + 16

We consider the new divisor 43 and the new remainder 16,and apply the division lemma to get

43 = 16 x 2 + 11

We consider the new divisor 16 and the new remainder 11,and apply the division lemma to get

16 = 11 x 1 + 5

We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get

11 = 5 x 2 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 419 and 42969 is 1

Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(43,16) = HCF(188,43) = HCF(231,188) = HCF(419,231) = HCF(42969,419) .
